FEED MECHANISM FOR BUTTON-ATTACHING MACHINES.

To all whom it mag concern:

Be it known that I, CHARLES, E. PARSO S, a citizenof the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Improvement in Feed Mechanism for Button-Attaching Machines, of which thefollowing isya .full, clear, and.

exact description. V

This .invention relates to a feed mechanism for button attaching machines, and is designed particularly for use in connection with machines for attaching tack fastened buttons, and is in the nature of a modification of the invention disclosed in the patent of Augustus'H. "Cosgrove, No. 1,499,203,

It is the object of this invention to provide means whereby the feed mechanism, in case it becomes jammed, maybe easily and expeditiously cleared of such obstructions and be quickly placed in operative 'condltion 'again.

In the patent above mentioned, a movable I part ,is provided in connectionwith the tack raceway,this part being adapted to be swung,

out of tack guiding position, whereby one side of tlietack raceway is opened for the removal of imperfect tacks orslugs orother obstructions. In the device of that patent,

the tack cutolf is arranged in fixed'relation to thetack chute, but I have "found that this cutoff may be so modifiedin construction as tobe capable of being mounted upon the movable portion ofthe raceway and be moved therewith so that when the movable portionis swung out of tack; guiding position, the whole of the tackifeeding raceway may be unobstructed.

"Tothisendthe invention consists in a feed mechanism for button setting machines "including a tack raceway *havingamovable portion adapted-to be swung out of tack guiding position, and a tack :cutoif carried by saidinovable portion and movable there with, as I will proceed now to explain and finally claim. i

Application filed August 29, 1923. Serial No. 659,997.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a fragmentary sectional side ele- ",VELlZ-lQll' showing an embodiment of my invention applied to a machine of the type described. Fig. 2 is a front elevation of a portion of the parts shown in Fig. 1. Fig. 3 is a rear elevation of the movable portion of the raceway detached with the tack cutoff carried thereby.

In the drawings I show the machine frame or head 1 carrying a setting plunger 2 and a setting anvil 3, and adjacent to the anvil '3 1s a table lupon which is mounted a plate 5 carrying a stand 6. This stand 6 is so formed as to provide one portion? of a tack raceway 8, and a support 9 for a tack chute 10. The tack raceway 8 is completed by means of a movable member 11 pivoted at 12 to an upright extension 13 of the stand 6 and having at its lower forward end a locking lip 14 formed for engagement with a oomplementally formed edge 15 on the plate 5. This engagement between the parts 14 and 15 prevents any direct vertical movement of the movable member 11, but per mits it to swing upon its pivot 12.

In order to prevent untimely movement of the member 11 upon its pivot 12, I provide a latch member 16 pivoted at 17 upon a stud 18, this latch member being formed for engagement with a notch or recess 19 in the horizontal portion 20 of the movable member 11, and provided with a handle 21 by which it may be readily swung upon its pivot To prevent undesired disengagementof the latch member 16 from the recess 19, I provide a dog 22 which engages with a complemental depression 23 in the plate 5. Proper engagement between the dog and its corresponding depression is assured by means of a spring 24 surrounding the stud 18 and bearing upon the latolrmember 16.

The upper end of the movable member 11 is formed 'to provide a 'camsurface 25 against which bears one end 26 of a stop member- 27 pivoted at 28'to the tack chute. This stop member is provided with a stop finger 29 which, when themovable member isswung to the position shown in dotted lines inFig. 2, will fall across the slot in the, tack chute through which the points or shanks of the tacks extend, and will prevent the tacks in the :chute =from sliding ClONVlLSLDlG.

All of the parts above describedaresubstantially i the same, .and operate insubstantially the same ,manner, as the corresponding parts or the device of the patent of Augustus H. Cosgrove mentioned.

Pivoted at to the movabieamember $1 1 is a tack cutoff 31 having an extension 32 which normally extendsflacross:theraceway 8, and the cutoff is recessed at 33 to form a catity substantially neonforming to the shape'o'f "the heads of the tacksiedto it. its will be seen, when the movable portion of the raceway is in the aposition shown in "full lines in Fig. 2, the cutoff lies flat against the bottom of theraceway so that its recess-33 Will-engage with the heads'of the tacks descendingthechute 10. The cuto'ft i-szprovided with an extension or arm Bet which carries *a pin 35 i normally engage d by a complemental pin 36 carried byaflink37 connected with an operating dever oscildated "by suitable mechanism (not shown) through a sh-aft 39 The arm 34 isfialso-proadded with a handle 40, and the inov-able =member 11 is provided with a similar han- -die -41, and "these handles, iin addition to their function as means 5 by Which the cutoff and -movable member may be conveniently grasped, respectively,serve as means for attachment of the-ends of 5a tension spring 7 -12 'whichnormally' retains the cutoff iil in 'raceway intercepting position.

It will, at course, be understood that oscillation of "the lever 38 causes reciprocation at the link 37 and through the pins 36 and transmits mot-ion to the' cutoff about its pivot 30, so that "upon each upward movementofthelever fiSythe cutoff 31 will be -moved to tack releasing position, and upon subsequent downward movement of *the lever 38 the spring 42 will "return the cutoff to raceway intercepting position. It may be noted here "that the'cutdft is prois moved "to tack releasing position, will lie across the discharge end 1 1 of the tack chute and will prevent egress *th'erefro n of the tacks therein.

ti-will thus be-scelrth-at i' lleflllilviibl'e'HIGU1- 'ber 11 and therutoif and its spring 12,

form a unitary "structure movable as suclr about the pivot 12 when it is *desired to clear the raceway 8 of imp effect tacks, slugs and other 'obstructions, and inasmuch as there is no direct connection between the 'link 87 and the 'cutoii, the connection between same being merely one of 1 contact between the pins 35 and *86, nothing needs to be "detached or un'faStened to permit movement "of the 1 member '11 about its 1 pivot 12, except of course that the ilatch member 16Emu=st first b'e niowsd outdfthe way.

As shown in full lines in the drawing, andin the dotted line position of-Eig. 2, the cutoffiis -at the limit-of -its raceway intercepting position as allowed by the contact ofthepin35 with the pin 36,-but iit is possible, when the movable member '11 and with it the cutoft l are movedlto the position shown in dotted lines in 'Fig. 2, that the spring "42 may turn :the cutoff slightly upon its pivot 30, and in order that this iturningamaybelimited so that the cutoff will not assume an undesired position with respect to the movable unember 1 1, I prowide the cutoff with a :stop "shoulder 45 adapted to -abut against the side of the unember 11 as shown in 'light dash and dot lines in the dotted position riniFig. -2.

By the-arrangement 0f the cutoff upon {the movable nneinber, whereby the-l'two =m ay I turn as aunit about the pivot of 1 the -movable member, it will be seen that 1 -am en abledto obtain 1 unobstructedaccess to the tack raceway, and even to the discharge end a e-of the tack chute, if desired, whil'ezt'it 'the same 1 time sacrificing moire of "the ectivemess of the operation 5 of the -machine 1 to ac- -'coinplisl1 thisvpurpose.

have herein'above described any i invention as applied specifically to a tac k feed rnech anismdbut, it is obvious that it may be equally well applied -to mechanism f'or feeding elements fother than tanks, and it will be understood that I do 'not 'consi der the invention as limited to the particular 1 embo di-meiit herein shown 7 and described, as it is obvious that various changes -may be unade therein without departing "from the spirit ofthe invention or the scope of the following: claims.
